PURPOSE:To facilitate regulation of the temperature of a radiator and to prevent boiling of the interior of a heat exchanger, by a method wherein, in addition to a main radiator such as floor panel, an auxiliary radiator is provided, and forced cooling can be effected by means of a fan. CONSTITUTION:A hot heater is constituted such that a heat exchanger 2, heated by a heating source, such as a combustion device 1, a pump 4, forcibly circulating hot water, and a main radiator 5 are interconnected. An auxiliary radiator 7 is connected through a valve device 6, and forced radiation is effected by means of a fan 8 to regulate the temperature of circulating water. This enables sharp reduction of the temperature of circulating water, in regulation of the temperature of the main radiator 5 and in prevention of boiling of the heat exchanger 2. Further, even if the combustion device 1 is continued to burn under a condition that the flow of the hot water to the main radiator 5 is disconnected for a long period of time, an increase in the radiating amount of the auxiliary radiator 7 enables prevention of boiling of the heat exchanger 2, and as a result, there is no fear of dry-burning occurring. |
